Add method TimeRange.__lt__().
Patch by: Brian Harring <ferringb@tigris.org>
The __lt__() addition may look superfluous, but it's
intentional--python sorting relies on __lt__() (just __lt__()); as
such for heavily sorted instances a __lt__() was added (TimeRange in
this case) for a slight reduction via avoiding cmp() invocation--cmp()
requires a nasty search of the various scopes/namespaces and requires
native python code interpretting the results; using '<' offloads that
into the interpreter itself which can do things far far faster then
native python equivalents.
